Basal skin cells frequently envelop axons at 78 hpf. TEM images of the wild-type zebrafish epidermis at 78 hpf. P, peridermal cell; B, basal cell; BM, basement membrane; m, mitochondrion. A: Axons were found between epidermal cells (asterisks) and enveloped within basal cells (arrow). B: Higher magnification of axon indicated by arrow in A. C: An enveloped axon. Many cell junctions join the skin cell membranes (arrowheads). D: Possibly two branches of the same axon, one in cross-section and the other in longitudinal section. Note that in axons in B–D a clearly defined axon membrane appears to be in contact with, but is distinct from, the epidermal cell membranes surrounding it. Scale bars = 1 μm in A; 0.2 μm in B–D.
